Peter Jackson to direct a Doctor Who episode?

Peter "Tolkien" Jackson has fanned rumours of directing an episode of the BBC's Doctor Who into something approaching inferno status after posting the above video to his Facebook account.

The short sees Jackson - a long-time Whovian - cleaning his Oscars collection, poking fun at the requests of Doctor Who's showrunner Steven Moffat for the New Zealander to direct an episode of the sci-fi show. Confusion ensues when none other than Peter Capaldi appears in the director's home, with an unwanted companion.

Given that the official Doctor Who account went on to share the video, could this be the clearest indicator yet that Jackson will finally take the opportunity to direct one of his favourite shows?
